v DRAWER-suns.

To all whomz't may concern:

Be it known that I, JOHN G.,WRIGHT, a

citizen kof the `United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Y Drawer-Slide, of

a description. My invention relates to improvements in drawer slides and has for an object to provide a simple, light and eiicient drawer supporting slide whose cost to manufacture isreduced to a minimum.

My invention contemplates the construction of a drawer slide of `sheet metal so that the frictional resistance of the sliding parts will be relatively small and wherein stickingand warping will be avoided. Y

Another object of my invention is to provide a slide which comprises coperating members so formed that either one :of them maybe applied to the drawer and the other to the casing.

Another object of my invention embodies l the use of a plurality of alined slides between kthe coperatingv drawer and casing member, thus allowing the use of smaller individual slide members and greatly facilioperation.

, With these and other objects and advantages, the construction herein shown and described will'be obvious to those skilled in the art from the disclosures herein given;

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described,and more particularly pointed out in the claims. f y

In the drawings, wherein like reference numerals indicate like parts throughout the views; v l

Figure 1 is a sectional view, showing the slide as applied to a drawer;-

v Fig. 2 is an enlarged fragmentary section through the slide of F ig.l l;

Fig. 4 is a perspective of the other ofthe slide members. K

' Referring'more particularly to the drawings, 1 indicatesV the side rand bottom walls of a-.slidablev 'casing or drawer opening, and 2 a drawer adapted to operate therein.

posed slides or guides, each composed of a pair of coperating members 3 and 4, one of Vwhich as 3, is a male member, and the other of which, as 4, is a female member. I have shown the male member as applied to the drawer and the female member applied to the casing, but it is to be understood that eitherof these'members may be secured to the drawer, and the other secured to the casing, and they will operate under both arrangements.

The male member 3 comprises a metallic strip, preferably of sheet metal, which has an upstanding rib or tongue 5 disposed 1ongitudinally thereof, said rib being formed by bending the metal upon itself lalong the line 6, said fold being preferably not a sharp one, so that there will belittle danger of thle metal splitting along the line of the fo d.

The base of the rib 5 is bent outwardly in opposite directions along the line 7, transversely to the rib 5 to form arms or wings 8, said arms having apertures 9 therein. adapted to receive suitable securing means therethrough, for attachment to the drawer or casing. l

The female slide lmember 4 comprises a strip, preferably of sheet metal, which has a pair of laterally spaced upstanding ribs 10 thereon, said ribs forming a groove ll therebetween, thev space between said ribs being substantially equalto the thickness of the rib 5 of the member 3 so that there will be no transverse play or lost motion between the groove 11 andthe tongue 5 when the cooperating parts are in assembling re-' lation. Y

The ribs 10 are formed by folding the metal longitudinally' of the strip along two parallel spaced lines 12. The bases of the ribs are bent outwardly in opposite directions along the lines 13 transversely of the ribs 10 to form arms or wings 14, said arms having apertures y15 therein, adapted to re? ceive suitable securing means therethrough for attachment to the drawer or casing.

One of the slide members is attached to the drawer and the other to the casing, so that the rib of the male member lies in a plane intermediate the groove 11 of the female member and is adapted to slide therein without any transverse play.

eine,

Eitherl of the slide members may be secured to the drawer and the other to the as illustrated in Fig. 1, wherein is shown av plurality of sets of slide members, one on each side ofthe drawer, the male members 3 being secured to the drawer, and

the female members 4 being secured to the casing, so as to cooperate with one another.

4Having thus described my invention, it is obvious that various'immaterial modifications may be made in the same without departing Yfrom the spiritl of my invention; hencefl do not wish to be understood as limn iting myself to the exact S form, arrangement, construction and combination of parts 'herein shown and described, or uses men-V tioned.

h'at 1 claim as new and desire to secure Vby Letters Patent is:

. of said members being adapted to be secured to said casing, andthe other of said members being adapted to be secured to said drawer, the tongue of said first mentioned member being adapted. to enterl said groove of said second member so that it engages the opposed facesof the ribs and to slide therein.

2. The combination withv a casing and a drawer, of a slide comprising a pair of me- .tallic members, one of said members being folded longitudinally upon itself to form an upstanding rib, the foot of said rib being outwardlyv extended in opposite directions transversely .to sa-id rib, the other of said members being folded longitudinally of itself along two parallel lines to form a pair of spaced upstanding ribs having a groove uniform in cross section throughout its lengththerebetween, the base of said ribs being` outwardly eXtende-drin opposite directions transversely of said. ribs, one of said slide members being adapted to be secured to said drawer, and the other of said Vslidemembers being adaptedvto be secured to said casing, whereby the rib of the iirst Y. mentioned slide member will enter and lie in said groove between the spaced ribs of said second mentioned slide member and be vguided and supported therein.

The combination with a casing and a drawer, of a slide comprising apair of metallic members, one of said members -being folded'longitudinally upon itself to form an upstanding rib of uniform cross section throughout its length, the footof said rib ybeing Voutwardly extendedvin opposite div rections transverselygof said rib, the other of said members being folded longitudinally of itself along two parallel' lines to form a pair of spaced upstanding ribs having a groove therebetween` of a uniform cross section throughout its'length., the base of said ribs being outwardlyextended in opposite vdirections transversely Y of saidf'ribs, the

height of said ribs being substantially equal to the .height of the rib of said first mentioned slide member, one of said slide members being adaptedvrto be Secured to said drawer and the other 'of said Slide members being adapted to be secured to saidV casing, whereby the rib of saidiirst ment-ioned slide member will lie injsaidgroove between and bear on" the spaced ribs of said second mentioned slide 'member and be guided 'and supported therein. A Y 3 Y L1.-'1`he combination with` a casing and a drawer, o fa slide comprising a pair of'metallic members,one of said members being folded longitudinally upon itself to'form an upstanding rib ofuniform cross section throughout its length, therfoot of'said rib being outwardly extended in oppositedirections transversely of said rib, the other of said members being folded longitudinally tioned slide member will lie between and bear upon theV spaced ribs of said second mentioned slide member and be guided and supg ported therein. f
